Answer:
limiting reactant started with/limiting reactant needed=
= 3.5 mol/3.5 mol=1:1
Explanation:
2H2 + 1 O2 ---> 2 H2O
from reaction 2 mol 1 mol
given 3.5 mol 2.5 mol
needed 3.5 mol 1.75 mol
Excess reactant O2, Limiting reactant H2.
Limiting reactant will be used completely.
So, limiting reactant started with/limiting reactant needed=
= 3.5 mol/3.5 mol=1:1
Answer:
The answer to your question is:
Explanation:
Ideal gases
PV = nRT
P = nRT / V
P = (1)(0.082)(303) / 0.5
P = 49.7 atm
Real pressure
P = V²(nRT)/ (V - nb) - an²
P = (0.5)²(1)(0.082)(303) / (0.5 - (1)(0.03219) - (1.345)(1)²
P = (6.2115)/(0.4678) - 1.345
P = 13.28 - 1.345
P = 11.93 atm
To convert temperature in terms of kelvin to celsius, we subtract 273 to the given temperature in kelvin. In this problem, the given is 49 kelvin, thus, 49 - 273 is equal to -224 degrees celsius. The asnswer is <span>-224 degrees celsius. Kelvin is the SI unit for temperature.</span>
Answer:
Table salt i might be wrong
Answer:
A. NaHCO₃
Explanation:
NaHCO₃ ⇒ NaOH + H₂CO₃
NaOH is a strong base and H₂CO₃ is a weak acid. Therefore, NaHCO₃ is a salt of a strong base-weak acid reaction. The salt is basic because carbonic acid (H₂CO₃) is a weak acid so it remains undissociated. So, there is a presence of additional OH⁻ ions that makes the solution basic.
Hope that helps.
